Re: yamaha 860 st
This could be the pre amp transistor or the power amp , it will need to be tested and other components tested also to make sure they are not causing the pre amp to fail or the power amp to fail
if its the pre amp it will be cheap , if its the power amp then it won't be cheap , other small components are cheap

Same problem here, low humming from far left and right speakers. Crank volume up to 40 gets rid. Shame this was is a good setup. Now to find my receipt and and make the most of the Aldi 3 year warranty. I have tried it in different poer outlets, with no discernible change, change func from ipod, to radio to aux same issue, my guess is faulty units
You need to A) define the hardware; B) consider what is common to the external inputs that could possibly affect their volume. Speakers are common to everything and have no way of knowing what the source is, so forget about them.
Look at every control and indicator. Understand what the mean and do. Lower the volume to something reasonable before flipping any switch you dont understand.
The reason why your receiver is going in protect is because there is a short circuit happening. This would either be on your speaker wires, speakers or receiver itself. What you want to do to check would be:
1. Unhook all sources and speakers from your receiver.
2. Turn on your receiver and crank up the volume to maximum, if your receiver does not shutdown or go on protect then the receiver is OK. If it does shutdown and go on protect then its an internal problem on the receiver and you would need to send that over to an authorized service center.
3. Hook up a source and 1 speaker. Play something from the source or the fm tuner, Crank Up the volume to about 46 or 47 volume. If the receiver does not shutdown, its good.
4. Hook up a second speaker and repeat the process until you encounter the pop and shut down
if for example you encounter the pop on the 4th speaker, try changing the speaker wires.
5. If the receiver still shuts down then it would be a short on the speaker itself and it would need to go to an authorized service center.
You may also need to change the speaker set up. Go to DISC setting (one of the top selections on the remote) make sure you have no Disc in the DVD player. When in this mode press setup on the remote. On this menu you will have a option to adjust the speaker volume.
I had to increase my speaker volumes to get better sound. This setting is not accessible if you try to do the set up in other than DISC setting. Be sure to check the SURROUND setting. The SURROUND button on the remote will toggle between stereo and surround as stated in a previous post.
The unit may be experiencing an overload caused by a short circuit, internally or externally. Try disconnecting all the speakers, then turning up the volume. If nothing happens, connect one speaker at a time and turn up the volume to see if you get more sound. You may have a speaker that has shorted internally and this will help you discover the bad one. However, if when you have all the speakers disconnected, and the unit still goes into protection mode with the volume up, then there is a problem with the unit itself.
Hope this helps, and please rate my advice, good OR bad.
